Here is an astrological aspectarian software program which may prove useful to astrologers and programmers both.
This program uses the Astrodienst Swiss Ephemeris (click here)
to do all planetary calculations. Please see Astrodienst's web page for the details of the
Swiss Ephemeris license (click here)
and other documentation.
SE_Aspectarian generates geo and helio longitudinal and declination/latitude aspectarian data between any two given dates for
all the planets and main asteroids, including exact aspects between these bodies and a specified natal chart or fixed zodiacal degree
- and more.
